Idol fandom's playground "Fan & Star" opened surprise support for Geum Dong-Hyun on the 16th. It is a large advertising project to celebrate his birthday on the 14th of next month.

Geum Dong-Hyun's birthday project will be carried out in cooperation with fans cheering for him. Success is determined by the number of rainbow stars donated by fans.

When 20,000 stars are gathered, a congratulatory video will be shown on the CM board (square column) of Hapjeong Station in Seoul. If it reaches 55,000 stars, a congratulatory video will also be shown on Shinokubo's display in Shinjuku, Tokyo, Japan. Also, super-special gifts such as large digital electronic boards in Jamsil, M-Screen in Hongdae, Media Facade in Myeong-Dong, and Seoul Bus Advertising are waiting for fans.
